Hi folks,

I got catkin to build using the cmake commands William was kind enough
to tell me about. The same workflow worked for genmsg, which is also
built. However, when I try to build gencpp, it fails to find genmsg:

I've indeed tried to set the gemsg_DIR variable, but it didn't make a difference

The genmsg package that I built does have the required cmake config file:


> [ankur@dhcppc1  ros-repo]$ rpm -qpl ros-genmsg-groovy-0.4.18-1.fc18.noarch.rpm | egrep cmake

> /usr/share/genmsg/cmake/pkg-msg-paths.cmake.in
> [ankur@dhcppc1  ros-repo]$

Would anyone have any hints on what's going on here? Am I missing
something?

I've asked the same question here on the forum[1], but not received any
replies yet.
